[HELP] Nsh crash very easily if I call ls in command line

[geniusdo]

Description

I ported nuttx on my stm32h743vi board with usb cdc console configured. Its very likely to crash if I call ls command in nsh but other command wouldn't cause the issue. And i tried to use serial console, it worked fine. Very weird. I am pretty new to nuttx. I wonder how do I find where the problem is. Any help or suggestion would be appreciated.

Hi @geniusdo try to increase the Stack Size, for boards with USB normally you will need a bigger stack
